1 1.1 Product Overview The Purpletooth® PT-209G/219G Direct Sequence Spread Spectrum (DSSS) Wireless Modem is a high performance wireless modem. It is designed to provide a long distance, high data rate and robust platform for applications. It offers data communication capabilities to application equipment via standard interfaces. Neither additional hardware nor software modification is required in the application equipment to work with PT-209G/219G. By using a pair of PT-209G/219G modems, users can transfer data between almost all types of equipment that use asynchronous serial interfaces. The small size and superior performance of PT-209G/219G make it an ideal solution for many applications. Typical examples are: Traffic control Remote monitoring Telemetry Remote camera/robot control Mobile video transmission Environmental monitoring Emergency rescue Premises security Logistics PT-209G is the standard version that conforms to the FCC, CE and China SRRC regulations. While PT-219G is an enhanced version that bears the UL Class 1 Division 2/ATEX Group 2 Category 3 safety classification in addition to the FCC, CE and China SRRC radio approvals. 1.2 Features Key features of PT-209G/219G: Operates in license-free frequency band Supports serial data I/O with handshaking and hardware flow controls Supports high speed and high throughput data transfers via USB and Ethernet ports Provides error-free data connections via built-in CRC-16 error detection and automatic re-transmission Offers high data rate and support long distance Adopts the advanced Direct Sequence Spread Spectrum (DSSS) technology to provide high interference immunity to protect on-air data from signal interferences and malicious data trappings Supports various data applications with efficient communication protocols Easy to use, plug-and-play without specific software requirement 1. General NOTE1: This manual has been provided as a guide and reference for installing and using PT-209G/219G wireless modems. It is assumed that users of PT-209G/219G modem have either system integration or system design experience.

5 3.1 Setting up Connections PT-209G/219G modems are shipped from REnex with a pre-configured setting. They can operate “out of the box”. Hence, the only thing users need to do is to make the appropriate connections between the modem and their equipment via the RS-232 port, the USB port or the Ethernet port, and then power up. The master and slave(s) shall communicate properly. For using the USB port, you may need to install a driver for the first time plugging in your system. Please follow the “Purpletooth® Family USB Driver Installation Guide” for the installation procedure. 3.2 Checking the Link After finishing the physical connection setup mentioned above, PT-209G/219G should be ready. If the performance of the communication link is not satisfactory or any linking problem is found, the following steps may help you locate the problem. Figure 3. Basic network mode. 1. Connect each modem to a serial port of a PC using direct RS-232 cable. 2. Start a terminal program such as Hyper Terminal (http://www.hilgraeve.com, it may be found in Microsoft Windows OS) for each serial port. Make sure the baud rate and data format settings agree with those of PT-209G/219G. 3. Characters typed at the master’s terminal should appear at that of the slave’s and vice versa. 4. The TX LED should flash during transmitting data to the RF link. 5. The RX LED should flash during receiving data from the RF link. 6. Adjust the modem separation and the antenna direction to locate positions with the best performance. 3. Setup PT-209G/219G NOTE 2: PT-209G/219G is highly sensitive to obstacles in its communication path. Make sure the communicating modems are in line-of-sight. Otherwise, the performance may drop significantly. NOTE 3: Antenna height is a critical factor. Try to put the antenna at a position as high as possible. Slave Master
